Key Takeaways
- • Mercuria Energy Group is suing the Baltic Exchange over alleged distortion of the TD3C tanker benchmark index, claiming losses in the hundreds of millions of dollars caused by the exchange's continued publication of the benchmark during the effective closure of the Strait of Hormuz.
- • The Strait of Hormuz closure, triggered by the U.S.-Israeli conflict with Iran beginning February 28, 2026, stranded approximately 2,000 ships and 20,000 seafarers in the Gulf, with only a handful of vessels willing to transit daily, creating historically volatile shipping conditions.
- • Mercuria argues the Baltic Exchange breached contractual and statutory duties by failing to suspend the TD3C index despite market conditions rendering it inaccurate and unreliable, causing extreme volatility that distorted freight derivatives markets relying on the benchmark.
- • The TD3C route, which measures voyages from the Gulf to China, no longer represents the underlying market it was designed to measure, according to Mercuria's court filing submitted to England's High Court on April 30.
- • The dispute exposes systemic risk in commodity shipping benchmarks and highlights the vulnerability of index methodologies to geopolitical supply disruptions affecting critical maritime chokepoints.
Summary
Mercuria Energy Group Ltd., one of the world's leading energy and commodity traders, filed suit against the Baltic Exchange—the global benchmark provider for shipping indices—over alleged distortion of the TD3C crude tanker index during the effective closure of the Strait of Hormuz. The court filing, dated April 30 and submitted to England's High Court, alleges that Mercuria has suffered losses in the hundreds of millions of dollars as a direct result of the exchange's continued publication of the TD3C benchmark despite market conditions that render it fundamentally unreliable.
The underlying disruption stems from the U.S.-Israeli military conflict with Iran, which commenced on February 28, 2026, and has effectively closed the Strait of Hormuz—one of the world's most critical energy chokepoints. The closure has stranded approximately 2,000 vessels and 20,000 seafarers within the Persian Gulf, unable to transit through the strait. Current conditions show only a handful of ships willing to make the passage daily, creating an artificial scarcity premium and extreme pricing volatility in tanker markets. The prior nine-week closure of the strait triggered a 60% surge in Brent crude prices, underscoring the economic magnitude of such disruptions.
Mercuria contends that the Baltic Exchange breached both contractual and statutory duties by maintaining publication of the TD3C index—which measures shipping costs for crude oil voyages from the Gulf to China—despite the route becoming economically inviable and non-representative of actual market conditions. The result, according to Mercuria's filing, has been "ongoing extreme volatility in the pricing of TD3C, which no longer accurately or reliably represents the underlying market it is intended to measure." This distortion has cascading effects through the freight derivatives markets, including forward agreements that allow investors to hedge or speculate on future freight rates. As a Baltic Exchange subscriber, Mercuria argues the exchange's methodology failure has exposed it to significant financial losses while undermining the integrity of markets dependent on accurate benchmarking.
The lawsuit highlights a structural vulnerability in commodity index governance: when geopolitical events materially alter market structure, the question of when and how benchmark providers should suspend or recalibrate indices remains contested. The Baltic Exchange's decision to continue publishing TD3C assessments during the Hormuz closure demonstrates the tension between maintaining index continuity and ensuring data fidelity—a critical distinction for institutional investors relying on these benchmarks for derivatives pricing, hedging, and portfolio management decisions.
